Archaeologist Menelaos Markides has excavated in Katydata (as well as the surrounding area), and this yielded 100 ancient tombs as well as many amphorae from the Bronze Age.

[3] One area (Laonarka) surveyed in the village in 2002 as a part of the TAESP yielded some red polished ware along with some bone (possibly human), as well as major pottery scatter from the Late Bronze Age.

[4] [3] The research team discovered that another area (Pano Limna) included an Archaic sanctuary and a substantial Late Roman settlement.

[3] The research team speculated that the significant numbers of figurines and rather sparse contemporary sherds could mean that they originated from a bothros from the sanctuary.

The main village church is dedicated to St John the Theologian (Greek: Άγιος Ιωάννης ο Θεολόγος) and was built in 1878.
